Define EligibilityVerifier for veterans

[thekaveman]

This model holds references to most of the content that is displayed for the Veterans flow. Focus on English copy only for the basic/existing UI (i.e. no modals etc.)

@thekaveman Should this issue also update the copy for the highlighted bulleted section?

This bulleted section's copy is not stored in EligibilityVerifier, it's called in

benefits/benefits/eligibility/views.py

Lines 111 to 117 in 5fba584

	if verifier.is_auth_required:
	if verifier.uses_auth_verification:
	identity_item.bullets = [
	_("eligibility.pages.start.login_gov.required_items[0]"),
	_("eligibility.pages.start.login_gov.required_items[1]"),
	_("eligibility.pages.start.login_gov.required_items[2]"),
	]

I think it should be covered in a separate issue and PR, b/c there's a bit going on.

That sounds good,
